Two men are charged in separate drug deliveries that caused fentanyl-related deaths of two Millersville men.

Millersville Borough police charged Joseph Colomba, 19, and Shawn Stanford, 34, last month with felony drug delivery resulting in death.

Colomba is already serving an 8-to-20-year sentence for supplying a fatal batch of heroin to a Lancaster County man in 2016, and related drug charges.

The recent charge regards the Feb. 5, 2017, death of a 34-year-old man found unresponsive at a Millersville home.

Police determined an acquaintance of the victim provided him the heroin, which she obtained from Colomba. The acquaintance, Angela Giambilis, also is charged with drug delivery resulting in death.

Police recently obtained information that outlined Colomba’s role in the death.

Stanford is charged with providing fentanyl-laced heroin to a 34-year-old man who died at a Kready Avenue home on Nov. 14.

Unused bags of heroin at the scene tested positive for heroin and fentanyl. An autopsy revealed fentanyl in the victim’s system.

Lancaster city police and Lancaster County Drug Task Force assisted in providing information on Stanford’s drug-dealing activities. The sale that led to the man’s death was traced to Stanford, who is at Lancaster County Prison on $250,000 bail.

Millersville Borough police Detective Jason Scott filed charges in both cases. Assistant District Attorney Barry Goldman approved charges.

Lancaster County Drug Task Force assisted in both investigations.
